Abstract
The authors recently found an interesting phenomenon in a glass lapping test with a silver lapping plate and n-dodecyltrimethylammonium chloride solution that the silver lapping plate was almost never worn during the lapping process even under the condition of large stock removal of glass. In order to apply this type of lapping to wide varieties of materials, it is indispensable to find out an appropriate surfactant which has the same effect as n-dodecyltrimethylammonium chloride does. If it is successful, the result would provide a key for clarifying the mechanism of this phenomenon. For that purpose, in the present work, the authors examined experimentally the effect of quaternary ammonium compounds solution on the glass and silver lapping behavior, and thus the following results were obtaind. When the silver is lapped using quaternary ammonium compounds having methyl groups, the same phenomenon as seen in the case when using n-dodecyltrimethylammonium chloride solution was clearly observed for any types of glass lapping plate.
